The IDsCaptureDriverBufferinterface is used to manipulate individual sound capture buffers, which are separate objects from the main driver object (which supports IDsCaptureDriver). The IDsCaptureDriver::CreateCaptureBuffermethod creates a sound capture buffer object and returns an IDsCaptureDriverBufferinterface.
The IDsCaptureDriverBufferinterface contains the following methods:
| IUnknown Methods | Description |
|---|---|
| AddRef | Increments the reference count. |
| QueryInterface | Retrieves pointers to supported interfaces. |
| Release | Decrements the reference count. |
| IDsCaptureDriverBuffer Methods | |
| GetPosition | Called to query the current position of the buffer. |
| GetStatus | Retrieves the current state of the buffer. |
| Lock | Retrieves a valid write pointer to the buffer. |
| Start | Puts the buffer into a capture state. |
| Stop | Causes the capture buffer to stop capturing. |
| Unlock | Releases a block of data to the driver. |
